[Wswss] RE: [VHF] Fwd:(Slightly Off Topic) Repeater Preamp For Use In RF Dirty Site

Putting a preamp on a receiver does not reduce co-channel or any
interference for that matter.  It will make it worse.  You need a filter.
This is one possibility: www.dci.ca.

My friend, Bob, KK6UE, is the curator of a 2 meter repeater in ~~DM04pg,
Thousand Oaks CA.

The repeater receiver is frequently bombarded by public service repeaters
near the 2m band and also has lower than desired sensitivity.




Among the 4 preamp URLs listed below?(2 from Ramsey, 1 from ARR, & 1 from
N6CA), which might be the best for his repeater operations? What other
preamps not listed might?help to minimize the co-channel interference?

bt73Pete, N6ZE?



Ramsey
PR100 - High Performance 2 Meter Preamp Kit

http://www.ramseyelectronics.com/cgi-bin/commerce.exe?preadd=action&key=PR10
0

other choice from them is
PR10
http://www.ramseyelectronics.com/cgi-bin/commerce.exe?preadd=action&key=PR-S
ERIES

or I would go with
http://www.anglelinear.com/gaasfet/gaasfet.html

and lastly
http://www.advancedreceiver.com/page5.html
